| 1 | 中美花生收获机械化技术现状与发展分析显示文摘收获是花生生产关键环节,用工量占整个生产过程60%以上,机械化收获是一个国家花生生产水平的重要体现。中国和美国同是世界重要的花生生产与出口大国,但因花生生产水平特别是收获机械化水平差距悬殊,从而导致花生出口的国际竞争力不同。美国两段式机械化收获方式及其先进的花生收获机械化技术,使花生生产高产优质高效、国际市场竞争优势明显,而中国多种花生机械化收获方式并存,收获机械化水平相对较低,从而制约了花生生产效益和出口竞争力。基于大量文献的系统分析、中国花生生产实地调研以及美国花生生产和收获机械化的实地考察与综合分析,综述了中国和美国花生生产及其收获机械化发展现状,分别阐述了中国和美国最新花生起收机、捡拾收获机等机器的类型、总体结构型式和主要性能参数等;分析了花生收获机械关键装置的结构原理与特点;综合分析了美国花生收获机械化发展历程以及快速发展的主要动因,中国花生收获机械化发展的主要制约因素;提出了中国花生收获机械化发展动态。对深入了解中国和美国花生收获机械化技术现况及其发展历程,进行中国花生收获机械化发展总结,在借鉴美国成功经验基础上因地制宜地采取措施,加速发展我国花生收获机械化,具有一定的参考价值。 | 陈中玉 高连兴 CHEN Charles BUTTS C L | 2017 | 农业机械学报2017,48,4: | 64 |

| 3 | 柑桔黄龙病的鉴定和柯赫氏定理(英文)显示文摘黄龙(梢)病被认为是世界柑橘生产上的毁灭性病害已超过一个世纪,但该病害的病原学至今还没有清晰地建立起来。根据16S rRNA基因序列分析,一组被称为'Candidatus Liberibacter species'的难培养细菌被认为与黄龙病相关。然而,要确定'Ca.Liberibacter spp.'是黄龙病病原的柯赫氏定理并没有真正完成。令我们担忧的是,近年来有些文献频频指出'Ca.Liberibacter spp.'是黄龙病的病原,其实该细菌与柑橘寄主的直接病理反应还没有完全确定。我们建议,在黄龙病病原学清楚之前,文献报道在这方面需要有准确的阐述。 | Chen J Deng X Civerolo E L Lee R F Jones J B Zhou C Hartung J S Manjunath K L Brlansky R H | 2011 | 植物病理学报2011,41,2: | 10 |

| 5 | 美国花生脱壳加工技术特点及启示显示文摘脱壳加工是花生进入消费领域前的关键环节,其技术与装备水平决定了花生果仁质量,关系到花生食品安全。美国先进而独特的花生脱壳加工技术,是其花生制品丰富及国际竞争力提升的重要原因之一。为发掘可供中国借鉴的技术和经验,在实地考察基础上,运用社会调查法、文献研究法和经验总结法,从美国花生脱壳概念、加工分类及其重要性入手,系统分析了美国花生脱壳加工方式、脱壳厂及脱壳加工装备、典型花生脱壳工艺及装备配置流程。分析了美国花生收储、脱壳和销售的产地化、一体化和工厂化脱壳加工等特点。总结了花生脱壳技术和设备的最新进展,包括果仁储藏技术、典型花生脱壳加工工艺等技术和在脱壳加工装备总体构成中增加花生与果仁处理设备、独立驱动多滚筒花生脱壳机分级脱壳等。分析了中国花生脱壳技术概况和向双滚筒循环脱壳、设备大型化发展等最新进展。针对中国花生脱壳加工的主要问题,在分析中国国情和借鉴美国花生脱壳加工经验的基础上,提出了进一步加强脱壳技术研究、提高花生预处理、果仁精选技术与储藏技术、建立适当规模的花生收储与脱壳中心和提高花生产业有序化等发展建议。 | 陆荣 高连兴 Chen Charles Butts C L | 2019 | 农业工程学报2019,35,11: | 8 |

| 7 | Pulmonary infection control window in treatment of severe respiratory failure of chronic obstructive pulmonary diseases: a prospective, randomized controlled, multi-centred study显示文摘Background Early withdraw from invasive mechanical ventilation (MV) followed by noninvasive MV is a new strategy for changing modes of treatment. This study was conducted to estimate the feasibility and the efficacy of early extubation and sequential noninvasive MV commenced at beginning of pulmonary infection control window in patients with exacerbated hypercapnic respiratory failure caused by chronic obstructive pulmonary diseases (COPD). Methods A prospective, randomized controlled study was conducted in eleven teaching hospitals' respiratory or medical intensive care units in China. Ninety intubated COPD patients with severe hypercapnic respiratory failure triggered by pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. When the pulmonary infection had been controlled by antibiotics and comprehensive therapy, the 'pulmonary infection control window (PIC window)' has been reached. Each case was randomly assigned to study group (extubation and noninvasive MV via facial mask immediately) or control group (invasive MV was received continuously after PIC window by using conventional weaning technique).Results Study group (n=47) and control group (n=43) had similar clinical characteristics initially and at the time of PIC window. Compared with control group, study group had shorter duration of invasive MV [(6.4±4.4) days vs (11.3±6.2) days, P=0.000], lower rate of ventilator associated pneumonia (VAP) (3/47 vs 12/43, P=0.014), fewer days in ICU [(12±8) days vs (16±11) days, P=0.047] and lower hospital mortality (1/47 vs 7/43, P=0.025).Conclusions In COPD patients requiring intubation and invasive MV for hypercapnic respiratory failure, which is exacerbated by pulmonary infection, early extubation followed by noninvasive MV initiated at the start of PIC window may decrease significantly the duration of invasive MV, the risk of VAP and hospital mortality. | Wang, C Zhan, QY Cao, ZX Wei, LQ Cheng, ZZ Liu, S Zhang, JL Chen, RC Luo, Q Niu, SF Zhu, L Wu, DW Fang, BM Wu, TH Wang, CZ Liu, YN | 2005 | Chinese Medical Journal2005,,19: | 6 |

| 10 | Immunogenetic factors driving formation of ultralong VH CDR3 in Bos taurus antibodies显示文摘The antibody repertoire of Bos taurus is characterized by a subset of variable heavy(VH)chain regions with ultralong third complementarity determining regions(CDR3)which,compared to other species,can provide a potent response to challenging antigens like HIV env.These unusual CDR3 can range to over seventy highly diverse amino acids in length and form uniqueβ-ribbon‘stalk’and disulfide bonded‘knob’structures,far from the typical antigen binding site.The genetic components and processes for forming these unusual cattle antibody VH CDR3 are not well understood.Here we analyze sequences of Bos taurus antibody VH domains and find that the subset with ultralong CDR3 exclusively uses a single variable gene,IGHV1-7(VHBUL)rearranged to the longest diversity gene,IGHD8-2.An eight nucleotide duplication at the 3′end of IGHV1-7 encodes a longer V-region producing an extended Fβ-strand that contributes to the stalk in a rearranged CDR3.A low amino acid variability was observed in CDR1 and CDR2,suggesting that antigen binding for this subset most likely only depends on the CDR3.Importantly a novel,potentially AID mediated,deletional diversification mechanism of the B.taurus VH ultralong CDR3 knob was discovered,in which interior codons of the IGHD8-2 region are removed while maintaining integral structural components of the knob and descending strand of the stalk in place.These deletions serve to further diversify cysteine positions,and thus disulfide bonded loops.Hence,both germline and somatic genetic factors and processes appear to be involved in diversification of this structurally unusual cattle VH ultralong CDR3 repertoire. | Thaddeus C Deiss Melissa Vadnais Feng Wang Patricia L Chen Ali Torkamani Waithaka Mwangi Marie-Paule Lefranc Michael F Criscitiello Vaughn V Smider | 2019 | Cellular & Molecular Immunology2019,16,1: | 4 |

| 16 | 纳米光子结构软膜紫外光固化纳米压印(英文)显示文摘紫外光固化纳米压印是实现纳米结构批量复制的一种新技术.其特点是低成本和高分辨,而且可以达到极高的套刻精度.为了得到大面积图案的均匀复制,可用聚二甲基硅氧烷(PDMS)制备透光的压印软模板.其母版图案可由高分辨率电子束曝光和反应离子刻蚀的方法在硅片基底上获得,然后用浇注的方法将图案转移到PDMS上.本实验特别发展了紫外光固化纳米压印适用于软膜压印的双层膜图型转移技术.该双层膜由廉价的光胶和聚甲基丙烯酸甲脂(PMMA)构成.对光胶层的压印可用普通的光学曝光仪实现.然后再将图案用反应离子刻蚀的方法转移到PMMA层中.为了证明方案的可行性,在两种不同材料的半导体基片上压印了三角晶格的光子晶体和准晶结构的图案,并用剥离的方法将它们转移到金属薄膜上,最后成功地进行了硅片刻蚀实验.相信这一纳米制做方法对大面积纳米光子结构和光学集成芯片的制造是普遍适用的. | SHI J WANG Z M BAO K PEROZ C BELOTTI M XU L P LUO C X SUN M H ZHANG B JI H OUYANG Q CHEN Y | 2006 | 纳米技术与精密工程2006,4,3: | 2 |
